King's Quest: Quest for the Crown is a 1984 adventure game, originally published for the IBM PCjr simply as King's Quest. The story and the general design of the game was developed by Roberta Williams.
The game was originally released simply as King's Quest, the subtitle "Quest for the Crown" was added to the game box in the 5th rerelease (1987), but did not appear in the game itself. The 1990 remake was renamed King's Quest 1: Quest for the Crown (King's Quest I on the box).
King's Quest is an adventure game where you play Sir Graham, a brave knight who is sent on a quest to retrieve three treasures that were stolen by deception and stealth: a shield that protects its bearer from invaders, a mirror that foretells the future, and a treasure chest that is forever filled with gold. If Graham takes these treasures back to the royal castle, then the ailing King Edward the Benevolent will hand over the crown. During his travels, Graham will meet characters that will either help or hinder him.
You move Graham around with arrow keys, and perform actions by typing commands into the game, usually a verb/noun sequence. Some of the puzzles in the game rely on fairy tales, and a good knowledge of them is needed to complete them.
